Main Memory; Video Memory; Replacing The Processor Chip - HP Vectra VA 6/xxx Service Handbook

Main Memory

The PC has three banks on the system board for installing main memory; banks
A, B and C. Each bank consists of two sockets. The PC is supplied with 16 or
32 MB of main memory (composed of two memory modules installed in any
bank). The PC uses 60-ns EDO DRAM.
Memory modules must be installed in identical pairs, so that each bank with
memory installed contains two memory modules of the same size and type
(both EDO, or both FPM).
Main memory can be installed up to a maximum of 192 MB.

Video Memory

The PC is supplied with 2 MB of video memory. An additional 2 MB of video
memory can be installed by adding a D3557B module in the video memory
socket. This will make a total of 4 MB. Alternatively, an additional 6 MB of video
memory can be installed by adding an MGA-MIL/MOD6 module in the video
memory socket (ordered from Matrox); this will make a total of 8 MB.
